Carbon fiber hardware usually stops traffic at PRI because of how it looks, but SPE Motorsport brought a setup this year that demands attention for how it works. At the 2025 show, they unveiled a new line of carbon-fiber intake manifolds for the S650’s Gen-4 Coyote and the 7.3-liter Godzilla that are engineered to survive where other composites fail. The focus here was on eliminating the glues and epoxies that can let go under high boost and thermal cycling.
Dan Snyder, owner of SPE Motorsport, explained the engineering philosophy behind the two-year development process. “We had heard about a lot of failure points with other carbon-fiber intakes. A lot of companies were doing epoxy flanges, but with the expansion and contraction of the carbon fiber, especially under boost pressure, that epoxy would eventually fail,” Snyder explained.
To solve this, SPE ditched the adhesive approach entirely. Their new system uses a “mono-plenum” design paired with five-axis-CNC-machined billet runners. Instead of bonding the materials, the assembly is mechanically bolted together using O-ring seals and custom Torx-drive titanium fasteners. This means the intake is fully serviceable — you can disassemble it for porting or cleaning without compromising the structure.
The strength numbers are staggering. “The cool thing is we came up with a way to lay up the carbon so that we can do what we call our mono-plenum. We’re basically sandwiching the carbon-fiber mechanically in between the flanges, so there’s no way for it to fail. We have a lifetime warranty on these, and we actually certify them up to 130 psi,” Snyder said. They even included an integrated burst panel to manage overpressure events, a critical safety feature for high-boost drag builds.
For the Godzilla platform, SPE improved the throttle body angle to make swaps into vintage muscle cars easier. On the Mustang side, they kept the fitment seamless. “On the S650, it is a direct replacement with the factory throttle body location, so if you already have a ProCharger setup or something like that, it will bolt right on,” Snyder said. “I feel like for the ’24 Mustang guys, it was a big deal to keep the double throttle body.” These carbon-fiber intake manifolds are available now for builders ready to push serious boost without fear of failure.
